The ADL5201 is a digitally controlled, variable gain, wide band-width amplifier that provides precise gain control, high IP3, and low noise figure. The excellent distortion performance and high signal bandwidth make the ADL5201 an excellent gain control device for a variety of receiver applications. The ADL5201 also incorporates a low power mode option that lowers the supply current.
For wide input dynamic range applications, the ADL5201 provides a broad 31.5 dB gain range with 0.5 dB resolution. The gain is adjustable through multiple gain control interface options: parallel, serial peripheral interface, and up/down.
Incorporating proprietary distortion cancellation techniques, the ADL5201 achieves an output IP3 of greater than 47 dBm at frequencies approaching 200 MHz for most gain settings.
The ADL5201 is powered on by applying the appropriate logic level to the PWUP pin. The quiescent current of the ADL5201 is typically 80 mA in low power mode. When configured in high performance mode for more demanding applications, the quiescent current is 110 mA. When powered down, the ADL5201 consumes less than 7 mA and offers excellent input-to-output isolation. The gain setting is preserved during power-down.
Fabricated on an Analog Devices, Inc., high speed SiGe process, the ADL5201 provides precise gain adjustment capabilities with good distortion performance and low phase error. The ADL5201 amplifier comes in a compact, thermally enhanced, 24-lead, 4 mm × 4 mm LFCSP package and operates over the temperature range of −40°C to +85°C.

Evaluation Kits (1)
ADL5201-EVALZ is a fully populated, 4-layer, FR4-based evaluation board. For normal operation, it require a 5 V power supply capable of delivering 500 mA and a 3.3 V power supply capable of delivering 1 mA. The 5 V supply is connected to the test loops labeled VPOS and GND. This is the bias for the main amplifier. The open collector outputs are connected to the main bias via the power plane. The 3.3 V supply is connected to the test loops labeled 3.3 V and GND. The RF input is applied to the SMA connector labeled INB-. The RF output is available at the SMA connector labeled OUTB-. A fully differential input and output is easily configured by removing R3 and R47, installing a zero ohm jumper at R4 and R48, removing T1 and T2 and placing jumpers across the transformer pads. The gain control options are controlled via the on board USB micro controller . The evaluation board can be programmed through the USB port of a PC running Windows XP or Vista with Microsoft .NET Framework 3.5 installed. The required control software can be downloaded from www.analog.com. Manual operation of the gain control functions is possible using the 3 pin headers and supplied jumpers. Power up is controlled using the 3 pin header labeled PWUP or an external control signal maybe applied using the SMA connector labeled PWUP.
Software & Systems Requirements
Tools & Simulations
ADIsimPLL enables the rapid and reliable evaluation of new high performance PLL products from ADI. It is the most comprehensive PLL Synthesizer design and simulation tool available today. Simulations performed include all key non-linear effects that are significant in affecting PLL performance. ADIsimPLL removes at least one iteration from the design process, thereby speeding the design- to-market.
ADIsimRF is an easy-to-use RF signal chain calculator. Cascaded gain, noise, distortion and power consumption can be calculated, plotted and exported for signal chains with up to 50 stages. ADIsimRF also includes an extensive data base of device models for ADI’s RF and mixed signal components.
ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. "Zero defects" for shipped products is always our goal.
